Short answer: the MoFi SourcePoint 8. It ranks #17 of 222 bookshelf speakers by sound quality, rated 4.5/5, at $2,594. The GR-Research NX-Bravo ranks #26, rated 4.4/5, at $1,540, $1,054 cheaper, which does not close the gap in sound quality.
The MoFi SourcePoint 8 is the deeper-bass pick. A bookshelf speaker with an 8 inch concentric driver, neutral sound, excellent imaging, and wide dispersion that forgives placement. Its bass reaches about 52Hz before falling 3dB, against 77Hz for the GR-Research NX-Bravo. The tradeoff: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out.
The case for the GR-Research NX-Bravo: A bookshelf speaker with unusually wide dispersion vertically and horizontally, very clean bass decay, and a neutral midrange that is easy to drive. The catch: Pointed straight on-axis there’s a deliberate ~5dB high-frequency bump meant to compensate for narrowing dispersion off-axis; it needs about 15° of toe-out (aimed to cross behind the listener) to sound balanced, which won’t suit every room layout.
Buy the MoFi SourcePoint 8. It is rated higher for sound quality, and the $1,054 saving on the GR-Research NX-Bravo is not enough to make up the difference.
